Bioelectrocatalytic reduction of H2O2 catalysed by lignin peroxidase from Phanerochaete chrysosporium (LiP) was studied with LiP-modified graphite electrodes to elucidate the ability of UP to electro-enzymatically oxidise phenols, catechols, as well as veratryl alcohol (VA) and some other high-redox-potential lignin model compounds (LMC). Flow-through amperometric experiments performed at +0.1 V v

A method for simulating the cooled gas turbine is demonstrated. Based on equations and other knowledge found in the literature, a first-law thermodynamic, non-dimensional model is established and implemented in the equation-solving, programmable software IPSEpro. Increasing the water vapor or carbon dioxide contents of the gas turbine hot gas is found not to have an impact on the Stanton number,

In this paper, a method of assessing water quality from satellite data is introduced. The composite pollution index (CPI) was calculated from measured chemical oxygen demand (COD) and nutrient concentration. The relationships between CPI and 240 band combinations of SeaWiFS water-leaving radiance were analyzed and the optimal band combination for estimating CPI was chosen from the 240 band combina

Various lines of evidence suggest a respiratory route of transmission of nephropathia epidemica (NE). To study the response of the respiratory tract in NE, fiberoptic bronchoscopy with bronchoalveolar lavage (BAL) was performed in 5 patients in the acute phase of the disease. Compared to a reference group of 15 healthy individuals, BAL fluid of NE patients contained significantly higher total numb

Six years ago we reported the discovery of a central place at Uppakra in southern Sweden which promised to be unusually rich and informative (Hardh 2000). At 40ha it already stood out as the largest concentration of residual phosphate in the whole province of Scania, with surface finds of Roman and late Iron Age metalwork (second-tenth century AD). Following this thorough evaluation, the project m

The blood group ABO gene codes for a glycosyltransferase that adds the ultimate monosaccharide to a glycoconjugate and forms the A or B blood group specific antigen. The DNA structure of the three major alleles of the human blood group ABO system was first described in 1990. This review describes the subsequent developments, including the increasing number of variants of these common alleles and t

Context. The stellar abundance ratio of Mg/Fe is an important tool in diagnostics of galaxy evolution. In order to make reliable measurements of the Mg abundance of stars, it is necessary to have accurate values for the oscillator strength (f- value) of each of the observable transitions. In metal-poor stars the MgI 3p-4s triplet around 5175 angstrom (Fraunhofer's so-called b lines) are the most p

Popular Abstract in Swedish Ojämnheter i vägen orsakar påkänningar i åkande fordon. För fordonstillverkare är det intressant att veta egenskaperna hos dessa vägojämnheter. Det är lämpligt att använda statistiska metoder för att analysera mätningar av vägytor/vägprofiler, dels eftersom mätningarna ger stora mängder data och dels eftersom vägytor har ett slumpmässigt beteende (från en 100 meter långRoad profiles are studied from a vehicle fatigue point of view. A wide range of roads have been measured: from smooth motorways to very rough gravel roads. It is observed that the road profiles consist of irregular sections, which makes the stationary Gaussian model unsuitable (Paper A). In Paper B, a method for automatic identification of such irregularities is presented. It is verified that the

Popular Abstract in Swedish Vår konsumtion av varor ger nytta på ett flertal sätt. Men samma varor ger också upphov till olika former av miljöpåverkan genom hela deras livscykel (från råvaruutvinning till slutligt omhändertagande). Vi vet erfarenhetsmässigt att det är bättre att förebygga ett problem än att reparera skadan efteråt och på samma sätt förhåller det sig med miljöproblemen. När det gälPolicies based upon Extended Producer Responsibility (EPR) aim to reduce the environmental impacts of products across their entire life cycle. The intent is to induce design changes in products and thus reduce impacts at source. This, by provision of incentives to producers through an extension of responsibility. Since the early 1990s, a number of countries have incorporated the concept of EPR int

The synthesis of two rigid polycyclic secondary diamines, bis-(2,3:6,7-iminodimethylene)anthraceneand bis-(2,3:6,7-iminodimethylene)-9,10-dicarboxyethenoanthracene,by means of Diels-Alder reaction between 1,2,4,5-tetra(dibromo?methyl)benzeneand maleimides followed by imide reduction, is described. Furthermore,these two cyclic secondary diamines undergo acylation with N-protectedamino acids, thus p

In this paper, I propose a relevance-theoretic account of the particles le, guo and zhe in Mandarin Chinese. Though conventionally regarded as aspect markers, on closer inspection they seem to contribute to a range of interpretations that cannot be subsumed under a semantic category or a specific temporal representation. The explanatory model presented in this paper builds upon relevancetheoretic

Differences in the incidence of hip fractures have been reported between urban and rural areas. In this population-based study the characteristics of fracture patterns between the city of Malmo and the nearby rural district of Sjobo were compared. A total of 782 individuals in Malmo and 486 in Sjobo were invited to participate. Fracture history for all invited was registered. The odds ratio for fr

Over the years, there has been much debate regarding the conformational behavior of flexible polyelectrolytes with electrostatic interactions described by the D bye-Huckel approximation. In particular, the electrostatic persistence length has been reported to depend both quadratically and linearly on the screening length as well as having no consistent power-law dependence at all. On the basis of

The phylogeny of two lichens, Cetraria obtusata from the Alps and Coelopogon epiphorellus occurring in the southern hemisphere is studied. A DNA-matrix based on ITS 1 and ITS 2 sequences of the rDNA is compared with a data set composed of morphology and secondary chemistry characters in phylogeny analyses using PAUP 4.0. The two data sets were entirely congruent. Neither Cetraria obtusata nor Coel
